Date: 1 May 2007 14:54:07 -0000 From: suresync@...il.com To: bugtraq@...urityfocus.com Subject: Disable website access for sites running Webspeed _edit.r Busy agents exploit. 1-5-2007 author: Eelko Neven discovered: 28-4-2007 tested: Windows 2000 server & Windows 2003 server Because of poor security in _edit.r it is possible to put all agents in busy mode. First you have to find the messenger execution url. For example: http://yourmachine.com/scripts/cgiip.exe/WService=wsbroker1 http://yourmachine.com/scripts/wsisa.dll/WService=wsbroker1 just add the following to the url: /_edit.r your url will look like this: http://yourmachine.com/scripts/cgiip.exe/WService=wsbroker1/_edit.r When you run the above url you put the agent into an infinite loop (Do While). If for instance your server runs 5 Broker Agents you just have to run above url 5 times and then all agents will be put in busy mode. From that moment on it's not possible to access that broker anymore.
